Regarding changing Control Channel Only to ON, I don't have that option. I have only OFF, Plan 1, Plan 2, Plan 3, Plan 4.

I don't understand the Plan 1, etc. Would one of those be equivalent to ON?
Choose Plan 1. Here is what the manual says about that:
Control Channel Only Mode
When this function is activated, trunking is performed using control channel data only. Voice channel (also known as "working channel") frequencies do not have to be programmed into memory. When using this feature, the scanner will display "CC" and channel activity indicator bars will not operate. This feature only applies to Motorola 800 MHz and 900 MHz systems.
To turn this function on, choose Motorola Type-2 800 MHz or 900 MHz or TYPE 1 by selecting TRUNK DATA - BANK NO. - TRUNK TYPE. Then set to the desired control plan by selecting TRUNK DATA - BANK NO. - CTRL CH ONLY.
You must choose one of 4 frequency plans before you begin to Control Channel Trunk. Note that the default, Plan 1, is the most common. Read the description of the Plans below for details on which may apply for you.
PLAN 1: Use Plan 1 if the last three digits of ALL the frequencies in use end in one of the following three digits: 125, 375, 625, or 875 (example: 856.1125, 860.7375, 859.6625, 855.8875).
PLAN 2: If the last three digits of frequencies less than 869.0000 end in one of the following three digits (125, 375, 625, or 875) AND if ANY other frequencies end in (000, 250, 500, or 750) use Plan 2.
PLAN 3: If the last three digits of ALL the frequencies in use end in one of the following three digits (000, 250, 500, or 750) use Plan 3.
PLAN 4: If the last three digits of frequencies less than 866.0000 end in one of the following three digits (000, 250, 500, or 750) AND if ANY other frequencies end in (125, 375, 625, or 875) use Plan 4.
